His senate office said in a statement that Donnelly was dedicated to representing the voiceless.

“Throughout his career, he fought to save others, protect the most vulnerable in our society, and give voice to working men and women across the Commonwealth. He was a staunch believer in the role of unions and government to protect workers, and he was well known for his efforts to advance justice and equality for all people no matter their race, religion, national origin, or sexual identification,” his office said.

Before running for office, he spent 35 years on the Lexington Fire Department and rose to the rank of Lieutenant.

He is survived by his wife Judy and his two sons Ryan and Keith, his daughter Brenna and five grandchildren.

Details on his wake and funeral arrangements will be announced when available.
